Engineered high-purity CaCO3 solutions, precipitated calcium carbonate, and nano-scale compounding agents delivering exceptional whiteness, tailored particle distribution, and eco-certified performance for Serbian manufacturing hubs.
Explore our top four precision-formulated calcium grades engineered for animal nutrition, polymer synthesis, coatings, and pulp processing across Belgrade, Vojvodina, and Central Serbia.
The Republic of Serbia stands as the premier manufacturing, agricultural, and logistics center within the Western Balkans. Fueled by sweeping modernizations, significant industrial foreign direct investments, and bilateral trade alignments, Serbian industrial producers are demanding elevated standards for non-metallic mineral fillers—most notably ultrafine Ground Calcium Carbonate (GCC), Precipitated Calcium Carbonate (PCC), and surface-treated Nano Calcium Carbonate.
From the intensive agricultural plains of Vojvodina to the automotive and plastics manufacturing clusters in Kragujevac, Niš, Šabac, and the Greater Belgrade Metropolitan Area, raw material specifications have transitioned from conventional limestone powders to specialized, high-purity, and chemically uniform calcium carbonate derivatives.
As a global premier manufacturer, Shandong Useen Calcium Co., Ltd. delivers unmatched manufacturing scale, pristine limestone deposit purity, and continuous particle-size control directly to Serbian industrial converters, guaranteeing batch consistency, regulatory compliance, and just-in-time cost efficiencies.
Tailored mineral formulations resolving specific rheological, structural, and chemical challenges for Serbian manufacturing sectors.
In Serbia's agricultural heartland (Novi Sad, Subotica, Zrenjanin), our food/feed-grade calcium carbonate delivers bioavailable calcium nutrition for poultry, swine, and dairy feedstuffs. With high calcium purity (>38.5% Ca element) and certified low heavy metals (Pb < 2ppm, As < 1ppm), it maximizes eggshell integrity and skeletal development.
Serving major automotive tiers and tire production facilities in Inđija, Kruševac, and Kragujevac. Useen's active Nano Calcium Carbonate serves as a semi-reinforcing functional nanofiller in rubber compounds, improving tire tear strength, dynamic modulus, and reducing rolling resistance without compromising elasticity.
Engineered for Serbian pipe extrusion plants and wire compounders. Our stearic acid-coated ultrafine GCC enhances impact strength, optimizes screw plasticization, lowers titanium dioxide (TiO2) masterbatch formulation costs, and improves surface gloss in rigid PVC window profiles and corrugated drainage pipes.
For construction adhesives and architectural sealant manufacturers in Belgrade and Central Serbia, our Nano Calcium Carbonate (15–40nm primary particle size) creates robust thixotropic networks, providing non-sag properties during vertical application, rapid elastic recovery, and superior UV aging stability.
Tailored for water-based emulsion paints, anti-corrosive primers, and road marking paints throughout the Balkan market. Our precipitated and ground grades offer high dry-hiding power, controlled oil absorption (16-22 g/100g), and excellent scrub resistance, lowering expensive pigment loading.
Modern printing paper and corrugated board operations along the Danube benefit from our high-whiteness (>95.5%) GCC slurries and dry powders, enabling high mineral retention, optimized ink receptivity, improved opacity, and notable energy savings during the paper sheet drying phase.
Shandong Useen Calcium Co., Ltd. specializes in a range of products, including nano-scale calcium carbonate, food-grade calcium carbonate, calcium oxide, calcium hydroxide, and light calcium carbonate. Our company owns 17 fully automated calcium oxide production lines, three calcium hydroxide production lines, and nine calcium carbonate production lines. Its annual output is 200,000 tons for nano-calcium carbonate, 200,000 tons for calcium hydroxide, 160,000 tons for light calcium carbonate, 360,000 tons for heavy calcium carbonate, and 1 million tons for calcium oxide.
Innovation is at the core of everything we do. In recent years, we have made significant investments in R&D, focusing on the development of new technologies and next-generation calcium products. Our company has established close "industry-university-research" cooperation relationships with well-known foreign industry experts, the Institute of Process Engineering of the Chinese Academy of Sciences, Tsinghua University, China University of Geosciences, Beijing University of Science and Technology, Shandong University, etc.
Through our industry-university-research partnerships, we have established strong capabilities in applied research, product development, and advanced process engineering. These collaborations allow us to continuously evolve, improve our formulations, and meet the changing demands of global industries.
